'Bev it known that I, OSCAR L. Jvnnas, a

citizen Vof the United States, residing at Newk Yorkh/Iills, in the county of Ottertail and State of Minnesota, have invented certain newand useful Improvements in Horse-Detachers and Vehicle-Locks, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to horse detaching devices and particularly to that class of detachers wherein the draft aniinals'are de tached from the vehicle by the operation of a lever or other manually operable device.

The primary object of my invention is to provide a horse detacher which sliallbe very simple in constructionv andeffective in operation and a further object 4of the invention is to provide means operable simultaneously with the detaching of the draft animals for applying a brake to the vehicle and for locking the frontaxle from rotatable nievement on its king bolt so as to prevent the vehicle from sluing around.

Other objects will appear in the course of the following description.

My invention'is illustrated inthe accompanying drawings, wherein- Figure 1 is a top plan view of the running gear of a wagon showing my detaching device applied thereto;

Fig. 2 isy a vertical longitudinal section vthereof;

Fig. 3 is a rear view of the front, axle, the

lower fifth wheel being partly in section to show the latch 17;

Fig. 4: is an enlarged vertical sectional view of the upper and lower fifth .wheelsand the latching means ;v

Fig. 5 isa perspective lview of the arcuate member for operating the retractors; and

Fig. 6 is afperspective view of the. detent for holding the bolt l17 from operation.

In the drawings it will be seen that I have shown the ruiming gear of a vehicle as coniprising or including the front axle 10, the rear axle4 11 and thereaches 12 which are connected to the rear axle by means of braces or in any other suitable manner. The reaches 12 are connected by means of a cross brace 12a. I do not Vwish to be limited to the particular construction of this running gear. The running gear also includes a fixed fifth wheel 13 which is operatively mounted upon the forward end of the running gear so as to be fixedl relative tothe body of the wagon and a fifth wheel 14 which is operatively connected to the axle to rotate therewith, the fifth wheel 14 beingl disposed beneath the fifth wheel 13 and in register therewith. lThe fifth wheel 1 3 is formed with a plurality of perforations 15 and attached to the fifth wheel 14: is a bolt casing 16 having therein a bolt 17 a spring 18, and a removable cap 19. f

wheel 14 are bolts 20 which are adapted to .is pivotally mounted between semi-circular irons 23 attached to the reach members 12 or the lever may be mounted in any other suitable Inanner. This lever above its point of pivotal connection is operatively connected to a semifcircular yoke 24 having a longitudinally extending slot 24a. This yoke and slot, but particularly the slot, are concentric to the fifth` wheels 13 and 14 but are disposed rearward of these fifth wheels and operatively connected to the lever in any vsuitable manner are the curved retractors 25.

' These retractors are longitudinally slotted as at 2F*L and operate upon` pins orv bolts27 projecting upward from the front axle. The outer ends `of the retractors, which are turned in opposite directions, are operatively vconnected to the bolts 20. It will now be obviousthat when the lever 22 is pulled back,

the retractors will-be drawn back and, op-y erating againstthe pins 27, will cause a retractionV of. the bolts to thereby release the draft animals. It will be obvious that'a' forward movement of the lever, however, will urge the retractors forward and the pins 27 will cause the forward `ends of the retractors to move laterally, 'thus'V prje'cting Abolt 1"?.

ing the bolts 2O to their operative position. Also'pivotally: connected to the lever is a rod 283L having at its end a plate 28. This plate is normally disposed immediately above the bolt 17 andbetiveen the end of the bolt casing and the fifth Wheel so that it prevents thefproje'ction of the lock- If, however, the lever be Withdrawn or retracted, the plate 28 Will be Withdrawn from above the llocking bolt and the locking lbolt Will be projected by the spring and lock into one of the perforations 15 of the fifth 'wheel 13, thus immediately locking the movable fifth 'wheel 13 to the fixed lifth wheel 14- and preventing any rotative movement of the front axle. The lever 22 moves over a sector Vrack 29 whose for Ward end is mounted upon the iront spring the vehicle and Whose rear end me" upon the running gear Vin any suita ner adjacent the transverse brace y rack being provided with notches and the llever being provided 'with a manl'zally aetuatable locking detent 30 of the usual form toA engage in these notches so that f 4 may be held in Aits retracted or pro ad position. This detent 30 is of cernsc counwted to a hand leverinounted upon tl. i upper end of the lever 22. A

l Disposed across the rear end of the reach members V12V i'oiavard of the rear axle isa brake beam 31 arrying on its ends the brake shoes 32. This brake beam has medially disposed rod 33 Whichextends forward and Visioperatively connected to the lever 22 above the pivot ofthe lever. Preferably this rod V33 is formed in two sections connected by a turn buckle 3st, or connected in any other suitable manner sor that the rod may be lengthened or shortened so as to adjust the brake shoes. Preferably also the brake beam is bracedfifrom the rod 33 by means of the aiiigular braces 35. The brake beam is guided upon the reach men'iben; 'lill v means of the straps 36 attached to the rl` members and arching over the brake beam.

The operationA ot my inwantion will be obvious from what has goneljie'tore. ".Vhen there is danger of an animal running away, and it is desired to detach the-animal from the vehicle, the lever 22, whtV h .'.lisposed behind the dash orin any other sui d.ble position, is rmlled rearwardly by the driver, thus retracting the bolts 2O and releasing the draft animals. Y it the saine time the detent plate 28 is retracted so that the bolt 1.7 .vill be projeted into engagement With the fixed f fth Wheel, thus locking the fifth Wheels to- Vgether and locking the front axlev from rotation in a horizontal plane. Simultaneously with this, the brake beam will be forced rearward andthe shoes brought into engagement With the rear Wheels, thus checking the sneed ofthe vehicle. the draft animals they may be again at- After a detachment of Y tached to the vehicle by unscrewing the cap `Having described my invention, lwhat, l
